What else can I help you with?
What liquid non metal has the same energy level of calcium?
Calcium has electrons in the 4th energy level. The only liquid that has valence electrons in energy level 4 would be BROMINE.
What is the highest occupied energy level of Ba?
4 energy levels with 2, 8, 8, 2 electrons in the energy levels.
How many valence electrons would an element with atomic number 56 have?
The element with atomic number 56 is barium, a group 2 alkaline earth metal. Its atoms have two valence electrons in the 6s sublevel.
How many valence electrons does alkaline earth metal have?
2
Where do electrons lost by metal atoms during the formation of ions come from?
When chemical bonds form, thermal energy supplies some of the energy needed to remove electrons from metal atoms. Also, energy is released as the electron associates with another atom. This energy contributes to the removal of electrons from metal atoms too; both processes happen simultaneously (as the electron moves away from the metal, it moves closer to the other atom. Because of this, there is a lower activation for the process than there otherwise would be). In some cases, the electron is not passed to another atom. This can occur when a high energy photon is absorbed, which ejects the electron from the metal.
Give the symbol for a metal that has two p electrons in its outermost energy level?
Be
Which element is an alkaline Earth metal with 2 electrons an the second level?
The element you are referring to is beryllium (Be). Beryllium is an alkaline Earth metal that has two electrons in the second energy level.
What liquid non metal has the same energy level of calcium?
Calcium has electrons in the 4th energy level. The only liquid that has valence electrons in energy level 4 would be BROMINE.
What is a valence shell of mg?
The valence shell of magnesium (Mg) contains 2 electrons in the outermost energy level. This is because magnesium is an alkaline earth metal with 2 valence electrons. These electrons are located in the 3s orbital in the third energy level.
What is the highest occupied energy level of Ba?
4 energy levels with 2, 8, 8, 2 electrons in the energy levels.
Are there seven electrons in the outermost energy level charicteristics of a metal?
No. That is characteristic of a nonmetal, specifically the halogens (group 17) on the periodic table.
How many electrons do alkali metal family have?
they all have a differnet number of electrons, but all have a charge of 1-
An atom contains seven electrons in its outermost energy level the atom is what?
The question is somewhat vague. If the question were written as an atom contains seven electrons in the outermost energy level and that outermost shell is a p-shell then the atom is a halogen. If the atom contains seven electrons in the outermost energy level and that outermost shell is a d-shell or f-shell then the atom is a metal.
What happens to electrons in photoelectric effect?
When you shine a certain level of light wavelength on metal, you can knock electrons off the atoms of the metal. This phenomenon was explained by Albert Einstein in 1905, for which he received a Nobel Prize in 1921.
How many valence electrons would an element with atomic number 56 have?
The element with atomic number 56 is barium, a group 2 alkaline earth metal. Its atoms have two valence electrons in the 6s sublevel.
Is it true that Seven electrons in the outermost energy level is characteristic of a metal?
No. That is characteristic of a nonmetal, specifically the halogens (group 17) on the periodic table.
The number of electrons in the outer energy level of aluminum?
It depends on what elements are involved. Iron has two electrons in its outer shell, Lead has four. While in a metal, the outer electrons flow freely over the surface of the solid, there is no net loss or gain of electrons, the atoms do not become ionized, and are considered to still have their original number of electrons.
